Overview
Max Load of a material determines how much load (Mass) every side of it can hold. You can obtain this information using the Item Stats functionality added to the game in the alpha 7.6. To do this, place the mouse over an item to see the Object Stats, including its Max Load.
Use
Max Load is used together with Mass to calculate Structural Integrity and therefore planning structures of any sort. To do so, divide Max Load by Mass of the block and round down the quotient.
Structural Integrity = RoundDown( Max Load ÷ Mass )
Example
The function of Max Load is easily explained using an example.
